Honestly, I'll go back and read this later, but I'll go ahead and tell you this is absurd.
We invited small satellites!!! Cameras in a little box that floats around the Earth are a no brainer at this point.
Do you know how many small satellites space x puts up in a single falcon launch? Falcon heavy? Well wait for starship, it'll blow your mind.
Google starlink. 💫
Musk's satellites perform an extremely limited function of transmitting bulk data over the Internet. You simply cannot imagine the capabilities and
functionality of small reconnaissance satellites.
I can.
I spent 5 years designing and building them for Planet Labs, after a 30 year career designing advanced space missions for NASA, DARPA, and "Other
Government" customers. Planet Labs now operates the largest fleet of privately owned Earth observation satellites around the planet.
That article you quoted contains some factual information but misses the main point and comes to the wrong conclusion.
The main point is that we are in the early stages of a revolution in space development, and the US is leading that revolution. That revolution is
happening because of two related developments, both of which originated in the US.
The first development was the invention of the cubesat, by a professor at Stanford University and another at California Polytechnic University at San
Luis Obispo ("Cal Poly-SLO") around the year 2000. The Stanford professor (Robert Twiggs) was a friend and colleague of mine when I was in graduate
school in the Department of Aeronautics and Astronautics at Stanford. His motive for the invention of the cubesat was so that university students
could have the educational benefit of designing, building, and flying a spacecraft in about the same time and for about the same cost as doing a
similar project with a small radio controlled airplane.
Once the cubesat idea took off, people started finding more and more uses for them beyond just educational purposes. By 2010, some other friends and
colleagues of mine I worked with at NASA--Chris Boshuizen, Will Marshall, and Robbie Schingler--decided they could design, build, and operate a 3U
Earth observation spacecraft cheaply enough and in large enough numbers to take a new image of the planet (at low resolution) once a day. In typical
Silicon Valley fashion, they formed the start up company Planet Labs and built their first spacecraft in a garage in Cupertino, CA. Now they are a
billion dollar company.
The second development was the creation of SpaceX, by Elon Musk. Elon is truly motivated by the idea of making humans a multi planetary species. In
order to do that, he realized that the cost of getting a kilogram of stuff to space had to be reduced by several orders of magnitude to make it all
affordable. Many people have had that realization since at least the 1950s, but Elon was the first one to have the right combination of brains,
money, and motivation to make it happen. Everyone knew that reusability of the launch vehicle was key to getting the cost down. He set out
methodically to make that happen. Today, the Falcon 9, with its recoverable and reusable first stage is by far the lowest cost way to get to orbit in
the commercial sector. It is what enables payload developers/operators like Planet Labs and Starlink to have a viable business model.
Once that business model got established, the more conservative users of space (i.e., the government) have slowly started evolving their thinking to
take advantage of new possibilities. The US Missile Defense Agency is developing a constellation of Low Earth Orbit satellites to detect and track
hypersonic missiles. That will make defense against hypersonic missiles a practical reality. The National Reconnaissance Office has a classified
contract with SpaceX to develop a constellation of hundreds of Low Earth Orbit satellites to detect and track surface and air based targets in real
time. They will probably include the ability to autonomously track moving targets.
And so on. Elon says that about 95% of all the mass going into space now flies on a Falcon 9. When Starship becomes operational (probably within a
year), he says that will go up to 99+%.
That will enable the next phase of the revolution. The cubesat that is currently affordable within the budget of a University department and measures
10 cm on a side and weighs 2 kilograms will become a cube 1 meter on a side and weigh several hundred kilograms. University astronomy departments are
already designing orbiting telescopes that will be many, many times more powerful than Hubble and cost a tiny fraction as much. Orbiting laser and
other directed energy weapon spacecraft will become possible. The US Marine Corp will finally get their Starship Trooper deployment to anywhere on
the planet in 60 minutes that they always wanted.
And so on.
So, it's true that against that background some of the traditional spacecraft component suppliers, like MOOG, are unable to keep up with demand.
